How to do Certificates on MultiDomain Exchange with Least Cost

[stanlyn]

Hi,
I'm hosting a bunch of domains on our Exchange 2016 mail server and was wondering how this can be done most efficiently in terms of costs and management.

Am I correct in thinking that each domain needs a cert for:
domain1.com

http://www.domain1.com

slaexchange.ad.domain1.com
ad.domain1.com
autodiscover.domain1.com
mail.domain1.com
ftp.domain1.com
smpt.domain1.com
imap.domain1.com

and again for domain2.com and domain3.com and on and on?

Can some of the certs be wildcards and some be ucc-multi-san? My experience has been best with ucc-multi-san certs, but costs are getting out of control. Exchange acts as though it doesn't like wildcard certs. I may be doing something wrong and need some advice.

Thanks, Stanley

In college, I frequently encounter this kind of issue. I think this is because I have a lot of studying to do and don't have time to complete my homework. Fortunately, I utilize a phd service where I can get academic papers of any complexity to be written. I am thankful to the guys from this company who have saved me numerous times. They are really experts.
